Doug, what brand would you recommend for a tranny that has a break/race clutches/aluminum drums that Rock auto sells?

I currently run JR1 synthetic. But in the past I’ve run Walmart Dexron with zero issues.

I had an issue with a flaired out bolt hole for the pump on my powerglide case several years ago. It was bleeding through and engaging my servo and wiping out my band. I was running Walmart brand Dextron 3 at the time because it was so easy to get and boy did the smell of it give me trouble. It has a smell to it like burnt clutches and made trouble shooting it hard. That’s the main reason I went back to type F.
